Development of Eco-Flux Laminated Strip for Air Atmosphere Brazing
The purpose of this study is to introduce and discuss flux laminated strip. Flux laminated strip can be used for air atmosphere brazing. The new product is fabricated by four processes: embossing of strip; multi bending of embossed strip; flux injection; and resizing of the material. This flux laminated strip exhibits similar melting characteristics to flux cored and flux coated alloys. The flux laminated strip eliminates the need for a separate fluxing operation that is typically needed when using bulk alloy. The product ensures the correct amount of flux during the brazing process and reduces the post-braze clean time. The ability to produce a quality joint while reducing the amount of pre-braze and post-braze operations make flux laminated strip an innovative Eco-braze-materials.
